Raws li cov txheej txheem aromaticity tau piav qhia ua ntej, cyclooctatetraene tsis muaj ntxhiab vim nws tsis ua raws li 4n + 2 π electron Huckel txoj cai(piv txwv li nws tsis muaj qhov khib. tus lej ntawm π electron khub). … Yog li, yog tias cyclooctatetrene yog cov phiaj xwm nws yuav ua rau muaj ntxhiab tsw qab, qhov xwm txheej tsis ruaj khov.
YPuas yog Cyclooctatetraene los tiv thaiv aromatic?
Cyclooctatetraene tshwm sim thawj zaug los ua antiaromatic, tab sis yog ib qho piv txwv zoo ntawm cov molecule uas siv cov geometry uas tsis yog-planar kom tsis txhob muaj kev puas tsuaj uas tshwm sim los ntawm antiaromaticity.
Vim li cas Cyclooctatetraene Dianion muaj ntxhiab?
Cyclooctatetraene hauv nws daim ntawv dianionic (COT(2-)) yog suav tias yog ua ib feem lossis tag nrho cov aromatic vimrau qhov tseeb tias, tsis zoo li nws qhov nruab nrab, nws txais cov qauv qauv. nrog CC daim ntawv cog lus sib npaug.
Vim li cas cyclopentadiene tsis muaj ntxhiab?
Cyclopentadiene tsis yog ib qho tshuaj tsw qab vim muaj cov pa roj carbon monoxide sp3 hybridized ntawm nws lub nplhaib vim nws tsis muaj qhov tsis cuam tshuam cyclic pi-electron huab… Tab sis, nws muaj 4n\pi electrons (n yog sib npaug rau 1 vim muaj 4 pi electrons). Li no, nws yog antiaromatic.
Cyclooctatetraene tsis yog planar li cas?
Koj yuav pom tias tsis zoo li benzene, cyclooctatetraene tsis yog hom phiaj, hloov nws siv "tub" zoo li. Yog vim li cas rau qhov tsis muaj qhov tsis txaus ntseeg yog qhov tsis tu ncua octagon muaj cov kaum sab hauv ntawm 135 degrees, thaum lub kaum sab xis sp2 feem ntau ruaj khov ntawm 120 degrees.
